Music-STAND.

To all whomc' may concern.'

`Be it known that I, ANDRE-w Zoirnifo, a citizen of the United States,and a resident of Passaic, county of Morris, and State of New Jersey,have invented certain new and useful Improvements in Music-Stands, ofwhich 'the following is a, specification.

This invention relates to an improved music stand which is adapted tobe, for the most part, contained in' one unitary structure which isadapted to be extended when required for use, and `also to be nested orassembled when it is not in use, so that a small compact article ispresented when itis not extended.

The inventionfurtherconsists of a music stand of this kind whichconsists of a casing which formsa part of the music `stand in additionto its function as a casing, and has' feet at the bottom and a stem atthe top` which can be projected fromthe casing,

preferably simultaneously, and similarly simultaneously withdrawn withinthe casing when desired.

The invention further consists of a casing which is adapted to receivethe leaf or sheet holderwhijch supports the music, which, for thispurpose, is made so that it can be folded.

The invention further consists of certain details of construction whichwill be hereinafter more fully described and finally embodiedin theclaims.`

rThe invention is illustrated in the accompanying drawing, in whichFigure 1 isa front view of the device with the casing shown in section.Fig. 2 is a side View, with the parts assembled, illustrating thecompact package formed by this devicewhen the parts are fully assembled.Fig. 3 is a detail, on an enlarged scale, of the sheet music holder,this view illustrating the hub portion with its front plate removed `andthe fingers-of the bottom section on the left hand side of the figurealso removed.V Fig. 4' is a perspectiveview of the bottom end of one ofthe fingers.

'lfhe `music stand is made up of members which are extended whenthestand is to be used, the preferred forni being tohave such extensible.members mounted in a casing which forms a part of `the support, inthedrawing the casing 10 being shown, this casing being preferably tubu-larand usually made inthe form of a cylinder. To properly supporttheeXtensible members I provide a frame which is securely fastened withinthecasing, theflower part of the frame acting. as a .support for thelegs, the frame including guides or slide-ways 11 which are channeled,as at 12,to receive the legs 13, these legs being `adapted to bewithdrawn within the casing whenthe device is folded,

these gears being preferably all actuated from a singleworm 17 on ashaft18, which Y shaft is mounted with one end in the bearing in the bottomplate 19 and' passes through the upper platefQO and is rotated by meansto be hereinaftermore fully described. In order to permit the divergenceor separation of the bottom parts of the legs when they are extend-ed Iprovide swinging 'guides 21 mounted in the bottom. platey 19 and adaptedto swing outward when the legs are divergent, this being possible byreason of vthe extensions 22 on the legs, each of these extensionshaving a curved top 23,'each extension being pivoted, as at 24, to' itsrespective leg, and when the curved portion is engaged by the gear it isswung so that its and form a substantial and positive support- .for the,music stand.

The shaft 18 can be rotated inv any desired way,but I preferto rotate itbyV means of gearing, the gear 25 being mounted on the shaft 18 `andthe` gear 26 beingplaced on a Ashort shaft `27 mounted in the bearing28,

whichlispreferably part lof the frame, and a handle 29 is the means bywhich the short shaft 27 is turned. VThe particular form of handle I.llhave illustrated comprises the crank handle 29 pivoted at 8O to theboss81 i on the shaft 2'?, so that when not in use the handle can beswung so that it extends into a cut-away part'32 in the casing and thewhole surface is substantially flush.

When the shaft is tobe rotated the han-V dle is swung upward, Vthe stud83 enters the opening 34 in the collar 81, and, the handle being'in theposition illustrated in Fig. 9, the" shaft can be rotated, since thehandle por@y tion 29is swung outside the surface ofthe casing. 1

shaft 18 is rotated toproject the legs fromV the bottom of the casingthe stem 35 is projected from the top. The sleeve 86 .1s mounted in aspider 39. which is preferably made as 'shown in Fig. 7, having threespaced arms so as to leave a space yfor the reception of the foldedsheet or music holder to be described hereinafter.

` lIn orderto permit a more elevated position 4for holding the music insuch position as is desired, I provide an extension 40 which is usuallymade so that it is frictionally h eld in the stem, such asby means ofthespring lips 41 illustrated in Fig. 5, the top part of the Vextensionbeing adapted to support the sheet or music holder and is usuallyprovided with a vlip 42'which enters a socket 43 on the rear of the-hubyor central portion of lthe sheet holder.

The sheet holder is made foldable,V the preferred form comprising a hubwith a rear plate'44 and a front plate 45, between these being arrangedthe center plate 46. Fingers 47 are made with transverse studs 48 which'tit'. into openings Y49 in the front and back plates and rest inrecesses in the middle or center plate 46, the' center plate'b'eing cutn bottom of music books or the like, which.

away so as to provide stops 50 which limit the outward swinging of thefingers,lbu't permit these fingers to be nested, as in Fig.

3, or they vcan be extended Vto form afanlike structure, as shown' inFig. 1. On each side ofthe sheet holderare the bottom sections which actto support the supports or bottom sections are preferably l' made sothat they fold over and inclose the folded lingers, as shown in dottedloutline in Fig. 1.

In Figs. 8 and 6 I show this part of the device more indetail, eachbottom section being mounted on a pivot 51 and having a' stidening rib52 with a lipbent around to form a knuckle or eye through which the pin51 passes. Secured to the stitiening or bottom rib 52 is a back plate 53which is lLshaped and has an additional bottom section 54 hingedthereto, and front section 55 is hinged to the front ofthe additionalbottom section, these parts being adapted to be vfolded,ras shown indotted outline in c Fig. 6, andwhen thus folded can be swung upward fromthe position shownin full lines in Fig.y 1 to the position shown indotted lines' in the samefigur'e, and when so folded can be slid intothe casing in the position shown at a in 7, for `which reason I preferto eliminate one of the arms of the'spider 89. i

,This Vstructure also permits -the extension 40 to be slid into placeresat?) in Fig. 7, so that when thus assembled and the shaft 18 turned towithdraw the stem 35, a suitable L:

lid, suchfas the lid-56, can beV closed over the upper end of thecasing. 1' i i ,Y It will be evident from this description that acomplete music stand can be quickly extended by turning the handle 29.and when'it is no longer desired for use all that it is vnecessary to dois to' fold upthe sheet holder at the top, slip it into its place in thecasing, `and the extension 40A is then slipped down into its place inthe casing, thefhandle v29 rotated to cause the withdrawal of the legsand of the stem, and-thelid 56 canthen be put in position and a-compactpackage is the result which can be carried inthe usual jmusic case ormusic roll. Y i v If desired, the bottom part of the casing can beclosed by a suitable cover 57. shown in'dotte'd outline at the bottom'ofFig. 2.

y Slight changes and gmodiicationscan be made inthe detailsofconstruction without departing from the scope -of theinvention. Iclaim:

1. A music stand comprising a lcasin,.f,ga

stem adapted'to proiectfrom the top of. the

casing, feet adapted to bev projected from the lbottom of the casing,`mechanism for projectingthe stem and the feet from the casing. said'means alsoincluding a structure which locks the stem" and legsin theiradapted to :be detachably secured.' to the top of the stem. f T if 2. Amusic stand comprising a tubular casing, arframe' 'in the casing,flegssliding 'in the frame, a stem sliding in the frame,
